Cross-cultural adaptation of the Quality of Life Index Spinal Cord Injury - Version III

OBJECTIVE To translate and culturally adapt to Portuguese the Ferrans and Powers Quality of Life Index Spinal Cord Injury - Version III and characterize the sample in relation to sociodemographic and clinical aspects. METHOD A methodological study with view to cross-cultural adaptation, following the particular steps of this method: initial translation, translation synthesis, back-translation (translation back to the original language), review by a committee of judges and pretest of the final version. The pretest was carried out with 30 patients with spinal cord injury. RESULTS An index of 74 items divided into two parts (satisfaction/importance) was obtained. The criteria of semantic equivalence were evaluated as very adequate translation, higher than 87%, and vocabulary and were grammar higher than 86%. Idiomatic equivalence was higher than 74%, experimental greater than 78% and conceptual was greater than 70%. CONCLUSION After cross-cultural adaptation, the instrument proved semantic, idiomatic, experimental and conceptual adequacy, in addition to helping the evaluation of the quality of life of people with spinal cord injury.

Completing contracts ex post: How car manufacturers manage car dealers

This article illustrates how contracts are completed ex post in practice and, in so doing, indirectly suggests what the real function of contracts may be. Our evidence comes from the contracts between automobile manufacturers and their dealers in 23 dealership networks in Spain. Franchising dominates automobile distribution because of the need to decentralize pricing and control of service decisions. It motivates local managers to undertake these activities at minimum cost for the manufacturer. However, it creates incentive conflicts, both between manufacturers and dealers and among dealers themselves, concerning the level of sales and service provided. It also holds potential for expropriation of specific investments. Contracts deal with these conflicts by restricting dealers decision rights and granting manufacturers extensive completion, monitoring and enforcement powers. The main mechanism that may prevent abuse of these powers is the manufacturers reputational capital.

On a series of Goldbach and Euler

Theorem 1 of Euler s paper of 1737 'Variae Observationes Circa Series Infinitas', states the astonishing result that the series of all unit fractions whose denominators are perfect powers of integers minus unity has sum one. Euler attributes the Theorem to Goldbach. The proof is one of those examples of misuse of divergent series to obtain correct results so frequent during the seventeenth and eighteenth centuries. We examine this proof closelyand, with the help of some insight provided by a modern (and completely dierent) proof of the Goldbach-Euler Theorem, we present a rational reconstruction in terms which could be considered rigorous by modern Weierstrassian standards. At the same time, with a few ideas borrowed from nonstandard analysis we see how the same reconstruction can be also be considered rigorous by modern Robinsonian standards. This last approach, though, is completely in tune with Goldbach and Euler s proof. We hope to convince the reader then how, a few simple ideas from nonstandard analysis, vindicate Euler's work.

(Re-) Shaping hatred: Anti-Semitic attitudes in Germany, 1890-2006

In this paper, we assess the determinants of long-run persistence of localculture, and examine the success of policy interventions designed to change attitudes.We analyze anti-Semitic attitudes drawing on individual-level survey results fromGermany s social value survey in 1996 and 2006. On average, we find that historicalvoting patterns for anti-Semitic parties between 1890 and 1933 are powerfulpredictors of anti-Jewish attitudes today. There is evidence that transmission takesplace both vertically (parent to child) and horizontally (among peers). Policy modifiedGerman views on Jews in important ways: The cohort that grew up under the Naziregime shows significantly higher levels of anti-Semitism. After 1945, the victoriousAllies implemented denazification programs in their zones of occupation. We usedifferences in these policies between the occupying powers as a source of identifyingvariation. The US and French zones today still show high anti-Semitism, reflecting anambitious botched attempt at denazification. In contrast, the British and Soviet zones,register much lower levels of Jew-hatred.

State capacity and military conflict

In 1500, Europe was composed of hundreds of statelets and principalities, with weak central authority,no monopoly over the legitimate use of violence, and overlapping jurisdictions. By 1800, only ahandful of powerful, centralized nation states remained. We build a model that explains both the emergenceof capable states and growing divergence between European powers. We argue that the impactof war was crucial for state building, and depended on: i) the financial cost of war, and ii) a country sinitial level of domestic political fragmentation. We emphasize the role of the "Military Revolution",which raised the cost of war. Initially, this caused more cohesive states to invest in state capacity, whilemore divided states rationally dropped out of the competition, causing divergence between Europeanstates. As the cost of war escalated further, all states engaged in a "race to the top" towards greater statebuilding.

Finite sample nonparametric tests for linear regressions

We introduce several exact nonparametric tests for finite sample multivariatelinear regressions, and compare their powers. This fills an important gap inthe literature where the only known nonparametric tests are either asymptotic,or assume one covariate only.

Fées et weise Frauen: les faiseuses de dons chez Perrault et les Grimm, du merveilleux rationalisé au merveilleux naturalisé

Dans «La Belle au bois dormant» et «Dornröschen», des personnages aux pouvoirs magiques déterminent l'avenir des héroïnes en leur accordant des dons positifs ou négatifs. La comparaison des textes montre toutefois que les fées et les weise Frauen (femmes sages), issues de traditions différentes, ne jouent pas les mêmes rôles dans les intrigues et que leurs actions ne sont pas présentées de la même manière. Si le conte de Perrault explique les motivations des fées et en fait des êtres réfléchis, le Märchen des Grimm représente les weise Frauen comme des figures énigmatiques appartenant à un univers où se déroulent des événements inexpliqués. Ainsi, le traitement de ces personnages féminins emblématiques reflète une volonté de rationaliser le merveilleux chez Perrault, contrairement aux Grimm, et témoigne ainsi de différences génériques, mais aussi historiques et culturelles plus larges. / Both in «La Belle au bois dormant» and in «Dornröschen», characters with magical powers determine the future of the heroines by endowing them with positive or negative gifts. The comparison of the two texts nonetheless shows that the fées (fairies) and the weise Frauen (wise women) -coming as they do from different cultural traditions- do not play the same role in the plot, nor are their actions presented in the same way. Whereas Perrault's conte explains the fairies' motivations and portrays them as rational beings, Grimm's Märchen depicts weise Frauen as mysterious women who belong to a universe of unexplained events. The treatment of these wondrous feminine figures thus testifies to a willingness to rationalise the marvellous in Perrault, and to present it as self-evident in Grimm, thereby reflecting generic as well as broader historical and cultural differences.

Policy making in divided government. A pivotal actors model with party discipline

This article presents a formal model of policy decision-making in an institutional framework of separation of powers in which the main actors are pivotal political parties with voting discipline. The basic model previously developed from pivotal politics theory for the analysis of the United States lawmaking is here modified to account for policy outcomes and institutional performances in other presidential regimes, especially in Latin America. Legislators' party indiscipline at voting and multi-partism appear as favorable conditions to reduce the size of the equilibrium set containing collectively inefficient outcomes, while a two-party system with strong party discipline is most prone to produce 'gridlock', that is, stability of socially inefficient policies. The article provides a framework for analysis which can induce significant revisions of empirical data, especially regarding the effects of situations of (newly defined) unified and divided government, different decision rules, the number of parties and their discipline. These implications should be testable and may inspire future analytical and empirical work.

Asymptotic behaviour of the density in a parabolic SPDE

Consider the density of the solution $X(t,x)$ of a stochastic heat equation with small noise at a fixed $t\in [0,T]$, $x \in [0,1]$.In the paper we study the asymptotics of this density as the noise is vanishing. A kind of Taylor expansion in powers of the noiseparameter is obtained. The coefficients and the residue of the expansion are explicitly calculated.In order to obtain this result some type of exponential estimates of tail probabilities of the difference between the approximatingprocess and the limit one is proved. Also a suitable local integration by parts formula is developped.

The modal nature of structures in ontic structural realism

Ontic structural realism is the view that structures are what is real in the first place in the domain of fundamental physics. The structures are usually conceived as including a primitive modality. However, it has not been spelled out as yet what exactly that modality amounts to. This paper proposes to fill this lacuna by arguing that the fundamental physical structures possess a causal essence, being powers. Applying the debate about causal vs. categorical properties in analytic metaphysics to ontic structural realism, I show that the standard argument against categorical and for causal properties holds for structures as well. Structural realism, as a position in the metaphysics of science that is a form of scientific realism, is committed to causal structures. The metaphysics of causal structures is supported by physics, and it can provide for a complete and coherent view of the world that includes all domains of empirical science.

Nationalisme économique et réalisme mercantile : la politique énergétique russe sous Poutine (2000-2008)

Mon travail met en évidence la restructuration de l'industrie énergétique russe sous les deux mandats Poutine (2000-2008) via le rôle prédominant de l'État dans une perspective historique. Une nouvelle élite politique russe (les Silovikis) issue des structures de force de l'Etat favorise le nationalisme économique axé sur le rétablissement de l'autorité du gouvernement central au sein de l'industrie énergétique nationale au détriment des pouvoirs régionaux, des sociétés privées étrangères et des oligarques indépendants. Dans cette perspective, on peut citer "l'affaire Youkos" en 2003 caractérisée par l'arrestation de l'oligarque Mikhaïl Khodorkhovsky; les tentatives silovikiennes de reprendre l'ascendant sur les compagnies pétrolières régionales Tatneft et Bachneft gérées par les gouvernements tatar et bachkir, la pression fiscale envers les majors pétrolières étrangères à l'instar du conflit russo- britannique relatif à la joint-venture TNK-BP. Quant à la politique énergétique étrangère russe, elle est inspirée par line vision réaliste mercantile; le gouvernement silovikien vise à défendre l'intérêt national, le prestige et la puissance de la Russie via ses "champions" énergétiques Rosneft et Gazprom utilisés comme levier politique, notamment à l'égard des pays de la CEI considéré par Moscou comme sa sphère d'influence historique. Dans cette perspective, nous pouvons mentionner l'interruption des approvisionnements pétroliers et gaziers russes à l'Ukraine, aux Etats baltes ou encore à la Géorgie; la concurrence entre les majors russes et étrangères en Asie centrale / Caucase pour les champs pétrolifères et les tracés de pipelines (nouveau «Grand Jeu»); la diversification des marchés russes à l'exportation à travers la promotion de nouveaux pipelines partant des champs pétrolifères sibériens vers la Chine et l'océan Pacifique.¦My work highlights the restructuration of the Russian energy industry under the 2 Putin madates (2000-2008) by the predominant role of the state in a historical perspective. A new Russian politic elite (Siloviki) from state structure forces promotes the economic nationalism focused on the reestablishment of the central governmental authority in the national energy industry against regional powers, private foreign companies and independent oligarchs. In this perspective, we can mention the "Yukos Affair" in 2003 with the arrest of the oligarch Mikhail Khodorkhovsky; the silovikian attempts to take over the regional oil companies Tatneft and Bachneft handled by the Tatar and Bashkir governments; the fiscal silovikian pressure against foreign companies such as the Russo-Britannic joint- venture TNK-BP. As for the Russian energy Foreign policy, it is inspired by a mercantile realism vision; the silovikian government aims to defend the national interest, the prestige and the power of Russia through its energy companies Rosneft and Gazprom as a political leverage especially toward the CEI Countries considered by Moscow as it historical sphere of influence. In this perspective, we can mention the interruption of Russian oil&gas supply toward Ukraine, Baltic states or Georgia; the competition between Russian and foreign companies in Central Asia/Caucasus for oil and gas fields and pipeline routes (new "Great Game"); the diversification of Russian export markets through the promotion ο new pipelines from Siberian oil&gas fields to China and the Pacific Ocean.

The State of the Immigrant Body and the Body of the State: Negotiations at the Interface

Using an ethnographic analysis of the social interfaces between state agents and Cape Verdean students in Portugal, observed through participant observation in medical appointments, social work, immigration services and legal support to immigrants, this article aims to examine disciplinary state practices and the negotiations and power struggles that take place. The ethnographic cases discussed demonstrate how the idea of a fair and neutral state is simultaneously reproduced and denied in practice, thus elucidating the state as a symbol of union of an effective disunity. The ethnographic examples also indicate other dimensions of state practice, besides micro-disciplinary powers, which create room for flexibility and adaptation. And it is in this sense that ethnographies of interfaces between state and citizen offer a more relative perspective of excessively systematic interpretations of governmentality, illustrating how the effects of contradictory state practices are as unpredictable as human action itself.

Contractual allocation of decision rights and incentives: The case of automobile distribution

We analyze empirically the allocation of rights and monetary incentives in automobile franchise contracts. These contracts substantially restrict the decision rights of dealers and grant manufacturers extensive contractual completion and enforcement powers, converting the manufacturers, de facto, in a sort of quasi-judiciary instance. Variation in the allocation of decision rights andincentive intensity is explained by the incidence of moral hazard in the relation. In particular, when the cost of dealer moral hazard is higher and the risk of manufactureropportunism is lower, manufacturers enjoy more discretion in determining the performance required from their dealers and in using mechanisms such as monitoring, termination and monetary incentives to ensure such performance is provided. We also explore the existence of interdependencies between the different elements of the system. and find some complementarities between completion and termination rights, and between monitoring rights and the intensity of incentives.

O Sistema Semi-Presidencialista Cabo-verdiano: A Relação entre os Poderes Executivo e Legislativo

O artigo procura analisar a relação que se estabelece entre o poder executivo e legislativo no sistema de governo cabo-verdiano, onde Investigadores buscam compreendê-lo, tendo em conta a sua configuração prática, teórica e constitucional. Há que realçar a proeminência do debate e dos estudos realizados no sentido de compreender como é que a academia científica procura debelar esta problemática. Duas questões são pertinentes neste debate: a primeira refere-se à configuração teórico-constitucional do sistema de governo cabo-verdiano e a outra à prática política e legislativa.

Improved statistical analysis of low abundance phenomena in bimodal bacterial populations.

Accurate detection of subpopulation size determinations in bimodal populations remains problematic yet it represents a powerful way by which cellular heterogeneity under different environmental conditions can be compared. So far, most studies have relied on qualitative descriptions of population distribution patterns, on population-independent descriptors, or on arbitrary placement of thresholds distinguishing biological ON from OFF states. We found that all these methods fall short of accurately describing small population sizes in bimodal populations. Here we propose a simple, statistics-based method for the analysis of small subpopulation sizes for use in the free software environment R and test this method on real as well as simulated data. Four so-called population splitting methods were designed with different algorithms that can estimate subpopulation sizes from bimodal populations. All four methods proved more precise than previously used methods when analyzing subpopulation sizes of transfer competent cells arising in populations of the bacterium Pseudomonas knackmussii B13. The methods' resolving powers were further explored by bootstrapping and simulations. Two of the methods were not severely limited by the proportions of subpopulations they could estimate correctly, but the two others only allowed accurate subpopulation quantification when this amounted to less than 25% of the total population. In contrast, only one method was still sufficiently accurate with subpopulations smaller than 1% of the total population. This study proposes a number of rational approximations to quantifying small subpopulations and offers an easy-to-use protocol for their implementation in the open source statistical software environment R.
